The Hungarian Forint is used in very large quantities ($1 USD = 218 Ft) so the government recycles a few tons of it every year. After shredding it and bundling it into bricks, the currency is shipped to charitable organizations to help with their heating cost.
I was able to build this lamp for under $20 (US) The books cost $6, The Switch and fixture cost $7.50, and a few misc. items that was another $4.
Another successful book lamp from a dedicated user! That particular light bulb looks brilliant, a great addition to the build. If you missed the first one, here's what user Richard C made last week. Well done guys, let's keep them coming!
